LOUIS DERNELLE, OF GHELTENHAM, MISSOURI.

BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No.327,867, dated October 6, 1885.

Application filed December 20, 1884. Serial No. 150,860.

To all whom it may concern.-

Be it known that I, LoUIs DERNELLE, of Cheltenham, St. Louis county, State of Missouri, have invented a certain new and useful Improvement in Brick-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a side elevation of the machine with part of the frame broken out. Fig. 2 is a top View. Fig. 3 is a vertical longitudinal section at 3 3, Fig. 4. Fig. 4 is a horizontal section at 4 4, Fig. 3. Fig. 5 is a front view with part broken away. Fig. 6 is avertical transverse section at 6 6, Fig. 3. Fig. 7 is a horizontal section at 7 7, Fig. l.

A is the main frame, which may have any suitable form.

B is the drive-shaft, carrying abelt-pulley, O, to receive the drivebelt. This shaft B carries a spur-wheel, D, that engages a spurwheel, E, of much larger diameter. The latter spur-wheel is upon a shaft, F. The wheel E has a wrist-pin, G, connected by a rod, H, with a pin, I, at the free end of a lever, J. This lever works on a fulcrum, K.

L is the brick-mold, which is fixed in the frame and has a movable bottom or plunger, M, having in the bottom a recess forming the bearing for the upper end of a toggle-bar, N, whose lower end has bearing in boxes 0 of the lever-head J. The arrangement is such that the oscillation of the lever imparts to the plunger M its required movement in the pressing of the brick. The upper plunger, P, works in guides R at its edges.

S is a bar passing through the plunger-head and through slots T in the main frame, and having wrist-pins S at its ends, connected by rods U with a bar, V, which extends through vertical slots W in the frame, and which is connected to the lower part of the lever-head J by links X.

Y Y are arms hinged to the lower plunger at Z, and whose lower ends are forced out ward by springs a.

b are lugs or projections 011 the inner sides of the rods U, which come in contact with the (No model.)

lower ends of the arms as the upper plunger, P, is rising after the pressing of the brick is completed. These lugs b work in vertical slots of the main frame, the lower ends of the arms also working in said slots. (See Figs. 5 and 6.) By means of the lugs 12 and arms Y the lower plunger is made to follow the upper plunger in its ascent, and the brick is thus raised from the mold until the top of the plunger is level with the top of the mold.

c is a floor or table level with the top of the mold, and which forms the bottom of the charger d at one side of the mold, while on the front side of the mold the table 0 forms the support on which the brick is carried as it is pushed from the top of the plunger M by the advancing end of the charger. This action of the charger is not novel, but is so well known as to require no further description.

The charger has the usual bottomless receptacle, which is carried beneath the hopper e to be filled and then over the mold to charge the same, in the usual manner. When the charger has nearly reached its advance position, the inclines f upon the sides of the charger come in contact with the upper ends, Y, of the arms Y and force them outward, drawing the lower ends of the arms inward and disengaging them from the lugs b, so that the plunger M falls by gravity and opens the mold for the reception of the clay. As the plunger M drops its downward mor emcnt is arrested by a bar, 9, hinged to the frame at its inner end, and supported at the other end upon an adjusting-screw, h, upon whose nut h the bar rests. The upper end of the screw it is secured to the main frame, and said screw passes through a slot or hole, g", of the bar. The position of this screw may of course be reversed; or it may screw in the bar and bear upon a point beneath.

The charger is moved by the camarms z and k, which are upon a rock-shaft, j. The

arms are on opposite sides of the wheel E, and

are actuated by studs Z and m upon the opposite sides of the rim of the wheel. These studs carry anti-friction rollers to ease their action on the arms. The upper cam-arm, z, is

connected by a rod, n, with the charger.

The machine has been described in its most simple formthat is to say, with a single brick-mold whereas in practice there would usually be two or more molds placed side by side with the ends outward.

The adjustable bar 9, by which the downward movement of the lower plunger, M, is regulated, is for the purpose of regulating the amount of clay received into the mold, according to the condition of the clay;

I claim as my invention 1. The combination, with the upper and lower plungers, of the vibrating lever J, fulcrumed at K, the toggle-bar N, interposed between the lower plunger, M, and the head J of said lever above its fulcrum, the rods U, connected at their upper ends to the upper plunger, P, vertical guides for confining said rods against lateral movement, and the togglelinks connecting the lower ends of said rods with the lower side of the head J of the lever J, substantially as and for the purposes set forth.

2. The combination of the under brickmold plunger with spring-arms, rods con- .nected to the upper plunger having projections acting on said springarms, and a chargor having inclines acting to release the arms from the projections, substantially as set forth.

3. The combination, with the upper and lower plungers and vertical guides for confining them against lateral motion, of the rods U, connected to the upper plunger, P, the arms Y, carried by the lower plunger, M, and adapted to be engaged by the rods Ufor elevating the lower plunger, as described, and the charger d, adapted to disengage said arms Y from the rods U, as and for the purposes set forth.

at. The combination, with the upper and lower plungers, of the rods U, connected to the upper plunger, provided with lugs or steps b, the arms Y, pivoted to the lower plunger, M, and adapted to be engaged by the said rods U, and the charger d, all constructed and arranged to operate substantially as set forth.

5. The combination of the main frame slotted at top and bottom, as described, the upper plunger, P, the paired rods U, the vibrating lever J, the toggle-link X, the toggle-bar N, and the lower plunger, M, all constructed and arranged to operate substantially as and for the purposes set forth.
